You've built up dozens of go-to prompts across ChatGPT, Claude, and Gemini. They're scattered across tabs, docs, and memory. PromptVault fixes that — one file, works offline, yours forever.
Every AI power user has the same problem. The prompts that save you hours are buried in random places — and you're either re-typing them from memory or starting from scratch every time.
You saved that perfect copywriting prompt somewhere in a shared doc. Now it's buried under 200 other lines and Ctrl+F is no help because you can't remember how you titled it.
Notion, Obsidian, or a dedicated "AI prompt" SaaS — they all want a monthly fee for what is, at its core, storing and searching text. That's not a subscription problem. It's a file problem.
You know the structure of your best SEO brief prompt. But memory degrades. Every time you reconstruct it from scratch, you lose something — and the output is a little worse each time.
PromptVault is a single HTML file you download once and open in your browser. No install, no account, no server. Your prompts live in your browser's local storage — on your machine, visible only to you.
Find any prompt in milliseconds by title, body text, or tag — no server roundtrip, no loading spinner. It's all local.
Organise with categories (Writing, SEO, Marketing, Code, Email, Social) plus free-form tags. Filter by either or search across both.
Every card has a Copy button. Click, paste into ChatGPT or Claude, done. No highlighting, no right-clicking, no friction.
Download your entire library as a clean JSON file. Import from any PromptVault export — duplicates are detected automatically.
Open the file in any modern browser — Chrome, Firefox, Safari, Edge. No internet required after you download it once.
Every prompt shows its character count — handy when working within model context limits or token budgets.
